DETAILED DESCRIPTION OF THE INVENTION

The present invention may be carried out on a gaming machine, as illustrated on FIGS. 1 and 2. Gaming machine 10 comprises display means 12 such as a video screen or a LCD screen controlled by a video controller, or mechanical reels controlled by a microprocessor; credit-receiving means 14 such as a card reader or a coin and/or bill acceptor; input means 16 such as electro-mechanic buttons, levers or touch screen controls; awarding means 18 such as a ticket printer, a card reader or a hopper; memory means 20; and game controller means 22.

Such a gaming machine 10 is designed, in its basic realization and as shown on FIG. 3, to receive credit information from a player (step 30) either in a physical format (such as coins or bills) or in an electronic format (such as a player card or a money transfer from a bank account), to receive activation information from the player (step 32), to randomly generate (step 34) and display (step 36) a game outcome, to evaluate said game outcome according to game rules (a pay table for example) (step 38), and to award a prize to the player for a winning game outcome (step 40).

On this gaming machine, reels are used to establish the indicia participating in the outcome. FIG. 4 provides an example of a ribbon 52 as used on a mechanical-reel gaming machine. Such reel 52 bears a plurality of imprinted indicia 54 in a predetermined order. A random selection of a reel stop position 56 determines at least one indicium to be displayed as part of the outcome; each one of these participating indicia 58 occupying a cell in the matrix. The determination of the indicia order may be controlled to prevent, or on the contrary encourage, the proximity of two occurrences of an indicium.

FIG. 5 presents the basic steps to conduct a line game according to the present invention. These steps comprise generating a game representation comprising a matrix of cells each bearing a randomly selected indicium (step 50), providing a template of cells in relative position with each other (step 52), said template comprising a reference cell, positioning the template on the matrix by superposing the template reference cell on a first indexing position (step 54) to establish a first template-outcome (step 56), and evaluating the first template-outcome participating indicia according to game rules (step 58). Afterwards, the method comprises selecting a new indexing position (step 60), thus applying once again the template on the matrix using said new indexing position (step 62) to establish a new template-outcome (step 64), and evaluating the new template-outcome (step 66). Then, an evaluation is performed (step 68) to determine whether the steps of selecting an indexing position, moving the template, establishing a new template-outcome, and evaluating this new template-outcome (steps 60, 62, 64 and 66) are repeated or not. Ultimately, an award is provided based on the template-outcome evaluations (step 70).

A first embodiment of the present invention uses a five-reel line game. As illustrated on FIG. 6 a, the resulting matrix 80 bears a plurality of indicia 82 in a three rows by five columns matrix. Beside the matrix 80 is illustrated the template 84 used to establish template-outcomes: an X-shaped template defining an arrangement of five cells 86 in relative position with each other and comprising a reference cell 94. In this example, the indexing positions 92 used to apply the template 80 are the second left cell 92 a, the center-reel cell 92 b, and the one located right to it 92 c on the center row of the matrix 80, resulting in three (3) template applications and thus three (3) template-outcomes 90. FIG. 6 b illustrates the indicia participating 88 in the template-outcome 90 using the first indexing position 92 a. According to the game rules, identical participating indicia establish a winning template-outcome. The evaluation of the template-outcome 90 illustrated on FIG. 6 b results in a loss. FIG. 6 c, with the second template-outcome 90, illustrates a winning outcome. Finally, FIG. 6 d, with a template-outcome 90 formed using the third indexing position 92 c, illustrates a losing outcome. An award is provided according to these results.

FIG. 7 a illustrates a similar game environment using a template 96 having a dimension corresponding to a partial vertical covering of the matrix 80. Therefore, the template 96 may be applied, without changing its orientation or wrapping the template, using six different indexing positions: a high-left position (FIG. 7 b), a low-left position (FIG. 7 c), a high-centered position (FIG. 7 d), a low-centered position (FIG. 7 e), a high-right position (FIG. 7 f), and a low-right position (FIG. 7 g). In this embodiment, the game rules establish that, to obtain a winning template-outcome, indicia participating in a template-outcome must share the same nature. Accordingly, since both identify indicia sharing the same nature (an animal nature for FIG. 7 b and a fruit nature for FIG. 7 e), FIGS. 7 b and 7 e illustrate winning template-outcomes. Each one of these two template-outcomes has a different value according to game rules, their respective value depending on the nature of the evaluated indicia.

FIGS. 8 a to 8 c illustrate a game where indicia on the reels are evaluated according to two of their characteristics: their nature and their background color. Game rules identify that a pay line evaluation is performed based on the indicia nature while a template evaluation is performed based on background color. When all indicia of a template-outcome share the same background color, the player is awarded a prize. In this embodiment, the template 100 illustrated on FIG. 8 a occupies the whole width of the matrix, resulting in two possible indexing positions: one identifying a high template position (FIG. 8 b) and one identifying a low template position (FIG. 8 c). FIG. 8 b presents a winning template-outcome comprising only indicia with a modified background color. Therefore, the player is awarded the value of this outcome.

FIGS. 9 a to 9 e illustrate the invention in a different game environment: a 3-by-3 matrix 81, wherein each indicium is established through an independent reel. FIG. 9 a illustrates the matrix 81 and the template 105 to apply on matrix 81. In this embodiment, applying the template 105 on the matrix 81 using the determined indexing positions, comprises rotating the template. FIGS. 9 b to 9 e illustrate these template orientations. According to game rules, identical indicia participating in a template-outcome result in a win. FIG. 9 b illustrates such a win. Furthermore, according to game rules, a winning template-outcome triggers the play of a bonus. The bonus game and its value may be the same regardless of the indicia triggering said bonus, or they might depend on the triggering indicia.

While the above embodiments present only game characteristics specific to the present invention, such games may be applied in games comprising regular line-game evaluations. Regular prizes on reel-based line games are usually evaluated through pay lines. In these line games, pay lines are activated through bets, one for each pay line. Active pay lines are evaluated once the indicia are randomly generated, and an award is provided for winning pay lines according to the evaluation of the “n” first indicia of a left-to-right or right-to-left reading of the pay line. Such embodiment may be illustrated through FIG. 9 a wherein each combination of five indicia following a horizontal configuration is a pay line. To play the game, the player places a bet value of at least three credits, each credit activating a horizontal pay line. Since one of the pay lines presents a Cat indicium on the first three reels when read from left to right, the player is awarded a prize for the bet applied on this pay line. The template is applied, as illustrated on FIG. 9 b, using at least one indexing position to generate at least one template-outcome which is then evaluated. The number of indexing positions used to apply said template may depend upon the bet value placed by the player or not. An award is provided to the player for a winning template-outcome.

In different embodiments, template evaluation may be influenced by different game modes. As example, template evaluation may be activated through the reach of a specific bet level. An example is a line game in which template-outcome evaluations are activated when the bet level placed on to play the game reaches a predetermined value.

The player may perform selections influencing template-outcome evaluations. For instance, the player may select a specific template or a criterion to evaluate the resulting template-outcomes. An example of template selection may be illustrated through FIG. 10 where the player is invited to select, prior to the indicia generation, which of a cross-shaped 112 or an X-shaped 110 template, both having the same number of cells, will be used to generate template-outcomes. The criterion evaluation may consist in deciding whether a template-outcome comprising only indicia sharing the same nature results in a win or a loss. This selection has an influence on the award provided for a winning outcome (template-outcome comprising only identical indicia), or on the number of cells comprised in the applied template.

This invention may be applied in a bonus, such as a series of free spins. Accordingly, regular pay line evaluations is performed during the regular portion of the game while template-outcome evaluations is performed during a series of free spins initiated by the occurrence of a triggering event during said regular portion of the game.

Another alternative embodiment, illustrated on FIG. 11, comprises “wrapping” the template around the matrix. Such a wrapping process may take place when the location of the indexing position does not allow the template to be entirely positioned on the matrix. The template cells that “fall” outside the matrix, through this process, are “wrapped” and identify matrix cells positioned at the opposite end of the matrix, keeping their relative position from each other. For illustrative purpose, the portions of the template falling outside the matrix and being applied at the opposite end of the matrix are illustrated in grey. According to this process, all template cells are applied on the matrix regardless of the used indexing position.

Throughout the disclosed embodiments, the award resulting from template-outcome evaluations may take different forms: credits, participation in a bonus game, free spins, progressive prizes, etc. Selection of the proper award form mostly depends on the desired incentive.

Those skilled in the art may recognize other embodiments and/or methods to provide such a game and/or functionalities, either through a central distribution of play data to networked gaming machines, a computer program adapted for such a game application and performing said game on computers, or program codes broadcasted using a suitable carrier or saved on memory, said program codes being suitable, when loaded on a computer or a gaming machine, for said apparatus to perform said game. However, all of such alternatives are intended to be incorporated in the present document through the herein reference.

It will be noted that the above embodiments illustrate different characteristics the present invention may present. Those skilled in the art will recognize that, even if the instant embodiments describe these characteristics as part of different embodiments, one could combine some of these characteristics. Furthermore, the invention may also present other characteristics and/or variations, with such characteristics falling within the scope of the invention, as set forth in the appended claims.

While the appended block diagrams illustrate the present invention as groups of discrete components communicating with each other via distinct data signal connections, it will be understood by those skilled in the art that the invention may be embodied through a combination of hardware and software components, with some components being implemented by a given function or operation of a hardware or software system, and many of the data paths illustrated being implemented by data communication within a computer application or operating system. The structure illustrated is thus provided for efficiency of teaching embodiments of the invention.
